On the basis of the following E° values, the strongest oxidizing agent is:
[Fe(CN)6]4– → [Fe(CN)6]3– + e–1; E° = –0.35 V
Fe2+ → Fe3+ + e–1; E° = –0.77 V

Al2O3 is reduced by electrolysis at low potentials and high currents. If 4.0 × 104 amperes of current is passed through molten Al2O3 for 6 hours, what mass of aluminium is produced? (Assume 100% current efficiency, atomic mass of Al = 27 g/mol) |
Answer |
Aluminium oxide may be electrolyzed at 1000°C to furnish aluminium metal (At. Mass = 27 amu; 1 Faraday = 96,500 Coulombs). The cathode reaction is |
Answer |
A certain current liberates 0.504 g of hydrogen in 2 hours. How many grams of oxygen can be liberated by the same current in same time? |

Answer |
Aluminium displaces hydrogen from acids, but copper does not. A galvanic cell prepared by combining Cu/Cu2+ and Al/Al3+ has an emf of 2.0 V at 298 K. If the potential of copper electrode is +0.34 V, that of aluminium electrode is |
